Mass And Heat Transfer

In order to analyze the performance of packed columns for dehumidification processes, calculation of the mass and heat transfer coefficients of the packing material used in the column is necessary. This paper is concerned with the interface transfer of heat and mass when air is brought into contact with the liquid desiccant mixtures. A theoretical study of heat and mass transfer analysis in an air-desiccant dehumidification contact system (packed column) employing liquid-desiccants, namely calcium chloride (CaCl2), lithium chloride (LiCl), and a new liquid-desiccant mixture (Cost-Effective Liquid Desiccant, CELD) consisting of 50 percent lithium chloride and 50 percent calcium chloride is studied. Mass and heat transfer coefficients for the gas and liquid phase, by use of 0.5-in., 1-in., 1.5-in., and 2-in. ceramic Rasching rings, are calculated. The findings for the three liquid desiccants are compared and discussed.

Mixture System

This article presents the results of an experimental study on the performance of a structured packing dehumidifier and the regenerator system. The system is tested using different proportions of an aqueous desiccant mixture of calcium chloride and lithium chloride solutions with an overall concentration of 40 wt%. The instantaneous effectiveness and the time-average effectiveness of the dehumidification process as well as the regeneration process are defined for the hybrid cooling system. It is found that as the lithium chloride content in the solution increases, the effectiveness of the dehumidifier as well as the regenerator increases. Moreover, the regeneration of the lithium chloride solution is found to be more effective than that of calcium chloride solution. The dehumidifier effectiveness using the desiccant mixture of 20 wt% CaCl2 and 20 wt% LiCl is found to be close to that of 45 wt% solution of calcium chloride and improves by ɛ80 per cent over the 40 wt% solution of calcium chloride.

Erysiphe Graminis Hordei

Earlier researchers have shown that the susceptibility of barley to infection by Erysiphe graminis hordei is enhanced by calcium ions but inhibited by lithium. Some effects of these ions on the infection process of E. graminis hordei in coleoptiles of barley were investigated in this study. Whereas 1 mM lithium chloride inhibited appressorial formation considerably and haustorial formation completely, these effects were totally offset by 10 mM calcium chloride. Moreover, whereas 5 and 10 mM lithium chloride inhibited both appressorial and haustorial formation completely, the former was offset considerably by 10 mM calcium chloride, but the latter was not.Sequential calcium chloride − lithium chloride or lithium chloride − calcium chloride treatments carried out at different times and for various durations showed that events occurring in coleoptiles 11 to 13 h after inoculation were most vulnerable to the treatments. These events correspond to infection stages involving the development of cytoplasmic aggregates, papillae, and haustoria. The data suggest that the two ions in question might compete for a common binding site in a reaction(s) associated with certain stages of appressorial and haustorial development.
